Definitions

  • the present invention relates to sulfonamides that act as modulators of the TRPM8 receptor.
  • the present invention also relates to processes for the preparation of sulfonamides and to their use in treating various diseases, syndromes, and disorders, including, those that cause inflammatory or neuropathic pain, cold intolerance or cold allodynia, peripheral vascular pain, itch, urinary incontinence, chronic obstructive pulmonary disease (COPD), pulmonary hypertension and anxiety, including other stress-related disorders, and combinations thereof.
  • COPD chronic obstructive pulmonary disease
  • TRP channels Transient receptor potential channels are non-selective cation channels that are activated by a variety of stimuli. Numerous members of the ion channel family have been identified to date, including the cold-menthol receptor, also called TRPM8 (McKemy D. D., et al., Nature 2002, 416(6876), 52-58). Collectively, the TRP channels and related TRP-like receptors connote sensory responsivity to the entire continuum of thermal exposure, selectively responding to threshold temperatures ranging from noxious hot through noxious cold as well as to certain chemicals that mimic these sensations. Specifically, TRPM8 is known to be stimulated by cool to cold temperatures as well as by chemical agents such as menthol and icilin, which may be responsible for the therapeutic cooling sensation that these agents provoke.
  • TRPM8 is known to be stimulated by cool to cold temperatures as well as by chemical agents such as menthol and icilin, which may be responsible for the therapeutic cooling sensation that these agents provoke.
  • TRPM8 is located on primary nociceptive neurons (A-delta and C-fibers) and is also modulated by inflammation-mediated second messenger signals (Abe, J., et al., Neurosci Lett 2006, 397(1-2), 140-144; Premkumar, L. S., et al., J. Neurosci, 2005, 25(49), 11322-11329).
  • TRPM8 on both A-delta and C-fibers may provide a basis for abnormal cold sensitivity in pathologic conditions wherein these neurons are altered, resulting in pain, often of a burning nature (Kobayashi, K., et al., J Comp Neurol, 2005, 493(4), 596-606; Roza, C., et al., Pain, 2006, 120(1-2), 24-35; and Xing, H., et al., J Neurophysiol, 2006, 95(2), 1221-30).
  • TRPM8 is also known to be expressed in the brain, lung, bladder, gastrointestinal tract, blood vessels, prostate and immune cells, thereby providing the possibility for therapeutic modulation in a wide range of maladies.
  • TRPM8 antagonists that can be used to treat a disease, syndrome, or condition in a mammal in which the disease, syndrome, or condition is affected by the modulation of TRPM8 receptors, such as pain, the diseases that lead to such pain, and pulmonary or vascular dysfunction.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to U.S. Provisional Patent Application No. 60/950,456, filed Jul. 18, 2007, which is hereby incorporated by reference in its entirety.
FIELD OF THE INVENTION
The present invention relates to sulfonamides that act as modulators of the TRPM8 receptor. The present invention also relates to processes for the preparation of sulfonamides and to their use in treating various diseases, syndromes, and disorders, including, those that cause inflammatory or neuropathic pain, cold intolerance or cold allodynia, peripheral vascular pain, itch, urinary incontinence, chronic obstructive pulmonary disease (COPD), pulmonary hypertension and anxiety, including other stress-related disorders, and combinations thereof.
BACKGROUND OF THE INVENTION
Transient receptor potential (TRP) channels are non-selective cation channels that are activated by a variety of stimuli. Numerous members of the ion channel family have been identified to date, including the cold-menthol receptor, also called TRPM8 (McKemy D. D., et al., Nature 2002, 416(6876), 52-58). Collectively, the TRP channels and related TRP-like receptors connote sensory responsivity to the entire continuum of thermal exposure, selectively responding to threshold temperatures ranging from noxious hot through noxious cold as well as to certain chemicals that mimic these sensations. Specifically, TRPM8 is known to be stimulated by cool to cold temperatures as well as by chemical agents such as menthol and icilin, which may be responsible for the therapeutic cooling sensation that these agents provoke.
TRPM8 is located on primary nociceptive neurons (A-delta and C-fibers) and is also modulated by inflammation-mediated second messenger signals (Abe, J., et al., Neurosci Lett 2006, 397(1-2), 140-144; Premkumar, L. S., et al., J. Neurosci, 2005, 25(49), 11322-11329). The localization of TRPM8 on both A-delta and C-fibers may provide a basis for abnormal cold sensitivity in pathologic conditions wherein these neurons are altered, resulting in pain, often of a burning nature (Kobayashi, K., et al., J Comp Neurol, 2005, 493(4), 596-606; Roza, C., et al., Pain, 2006, 120(1-2), 24-35; and Xing, H., et al., J Neurophysiol, 2006, 95(2), 1221-30). Cold intolerance and paradoxical burning sensations induced by chemical or thermal cooling closely parallel symptoms seen in a wide range of clinical disorders and thus provide a strong rationale for the development of TRPM8 modulators as novel antihyperalgesic or antiallodynic agents. TRPM8 is also known to be expressed in the brain, lung, bladder, gastrointestinal tract, blood vessels, prostate and immune cells, thereby providing the possibility for therapeutic modulation in a wide range of maladies.
International patent application WO 2006/040136 A1 from Bayer Healthcare AG purportedly describes substituted 4-benzyloxy-phenylmethylamide derivatives as cold menthol receptor-1 (CMR-1) antagonists for the treatment of urological disorders. International patent application WO 2006/040103 A1 from Bayer Healthcare AG purportedly describes methods and pharmaceutical compositions for treatment and/or prophylaxis of respiratory diseases or disorders. International patent applications WO 2007/017092A1, WO 2007/017093A1 and WO 2007/017094A1, from Bayer Healthcare AG, purportedly describe benzyloxyphenylmethyl carbamate, substituted 2-benzyloxybenzoic acid amide and substituted 4-benzyloxybenzoic acid amide derivatives for the treatment of diseases associated with the cold menthol receptor (CMR), a.k.a. TRPM8.
There is a need in the art for TRPM8 antagonists that can be used to treat a disease, syndrome, or condition in a mammal in which the disease, syndrome, or condition is affected by the modulation of TRPM8 receptors, such as pain, the diseases that lead to such pain, and pulmonary or vascular dysfunction.

As used herein, with reference to substituents, the term “independently” means that when more than substituent is possible, the substituents may be the same or different from each other.
As used herein, unless otherwise noted, the term “alkyl” whether used alone or as part of a substituent group, refers to straight and branched carbon chains having 1 to 8 carbon atoms. Therefore, designated numbers of carbon atoms (e.g. C1-8) refer independently to the number of carbon atoms in an alkyl moiety or to the alkyl portion of a larger alkyl-containing substituent. In substituent groups with multiple alkyl groups such as (C1-6alkyl)2amino- the C1-6alkyl groups of the dialkylamino may be the same or different.
As used herein, unless otherwise noted, the term “alkoxy” refers to an —O-alkyl group, wherein the term “alkyl” is as defined above.
As used herein, unless otherwise noted, the terms “alkenyl” and “alkynyl” refer to straight and branched carbon chains having 2 or more carbon atoms, wherein an alkenyl chain contains at least one double bond and an alkynyl chain contains at least one triple bond.
As used herein, unless otherwise noted, the term “cycloalkyl” refers to saturated or partially saturated, monocyclic or polycyclic hydrocarbon rings of 3 to 14 carbon atoms. Examples of such rings include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl and adamantyl.
As used herein, unless otherwise noted, the term “heterocycle” refers to a nonaromatic monocyclic or bicyclic ring system having 3 to 10 ring members and which contains carbon atoms and from 1 to 4 heteroatoms independently selected from the group consisting of N, O, and S. Included within the term heterocycle is a nonaromatic cyclic ring of 5 to 7 members in which 1 to 2 members are nitrogen, or a nonaromatic cyclic ring of 5 to 7 members in which zero, one or two members are nitrogen and up to two members are oxygen or sulfur and at least one member must be either nitrogen, oxygen or sulfur; wherein, optionally, the ring contains zero to one unsaturated bonds, and, optionally, when the ring is of 6 or 7 members, it contains up to two unsaturated bonds. The carbon atom ring members that form a heterocycle ring may be fully saturated or partially saturated. The term “heterocycle” also includes two 5 membered monocyclic heterocycloalkyl groups bridged to form a bicyclic ring. Such groups are not considered to be fully aromatic and are not referred to as heteroaryl groups. When a heterocycle is bicyclic, both rings of the heterocycle are non-aromatic and at least one of the rings contains a heteroatom ring member. Examples of heterocycle groups include, and are not limited to, pyrrolinyl (including 2H-pyrrole, 2-pyrrolinyl or 3-pyrrolinyl), pyrrolidinyl, imidazolinyl, imidazolidinyl, pyrazolinyl, pyrazolidinyl, piperidinyl, morpholinyl, thiomorpholinyl, and piperazinyl. Unless otherwise noted, the heterocycle is attached to its pendant group at any heteroatom or carbon atom that results in a stable structure.
As used herein, unless otherwise noted, the term “benzo-fused heterocycle” refers to a 5 to 7 membered monocyclic heterocycle ring fused to a benzene ring. The heterocycle ring contains carbon atoms and from 1 to 4 heteroatoms independently selected from the group consisting of N, O, and S. The carbon atom ring members that form the heterocycle ring may be fully saturated or partially saturated. The benzo-fused heterocycle ring is attached to its pendant group at a carbon atom of the benzene ring.
As used herein, unless otherwise noted, the term “aryl” refers to an unsaturated, aromatic monocyclic or bicyclic ring of 6 to 10 carbon members. Examples of aryl rings include phenyl and naphthalenyl.
As used herein, unless otherwise noted, the term “heteroaryl” refers to an aromatic monocyclic or bicyclic aromatic ring system having 5 to 10 ring members and which contains carbon atoms and from 1 to 4 heteroatoms independently selected from the group consisting of N, O, and S. Included within the term heteroaryl are aromatic rings of 5 or 6 members wherein the ring consists of carbon atoms and has at least one heteroatom member. Suitable heteroatoms include nitrogen, oxygen, and sulfur. In the case of 5 membered rings, the heteroaryl ring preferably contains one member of nitrogen, oxygen or sulfur and, in addition, up to three additional nitrogens. In the case of 6 membered rings, the heteroaryl ring preferably contains from one to three nitrogen atoms. For the case wherein the 6 membered ring has three nitrogens, at most two nitrogen atoms are adjacent. When a heteroaryl is bicyclic, at least one heteroatom is present in each ring. Examples of heteroaryl groups include furyl, thienyl, pyrrolyl, oxazolyl, thiazolyl, imidazolyl, pyrazolyl, isoxazolyl, isothiazolyl, oxadiazolyl, triazolyl, thiadiazolyl, pyridinyl, pyridazinyl, pyrimidinyl and pyrazinyl. Unless otherwise noted, the heteroaryl is attached to its pendant group at any heteroatom or carbon atom that results in a stable structure.
As used herein, unless otherwise noted, the term “benzo fused heteroaryl” refers to a 5 to 6 membered monocyclic heteroaryl ring fused to a benzene ring. The heteroaryl ring contains carbon atoms and from 1 to 4 heteroatoms independently selected from the group consisting of N, O, and S. Examples of heteroaryl groups with the optionally fused benzene rings include indolyl, isoindolyl, indolinyl, benzofuryl, benzothienyl, indazolyl, benzimidazolyl, benzthiazolyl, benzoxazolyl, benzisoxazolyl, benzothiadiazolyl, benzotriazolyl, quinolinyl, isoquinolinyl and quinazolinyl. Unless otherwise noted, the benzo-fused heteroaryl is attached to its pendant group at any heteroatom or carbon atom that results in a stable structure.
The term “halogen” or “halo” refers to fluorine, chlorine, bromine and iodine.
The term “formyl” refers to the group —C(═O)H.
As used herein, unless otherwise noted, the term “alkylsulfonyl,” refers to the group —S(O)2—R′ where R′ is an alkyl group as previously defined.
As used herein, unless otherwise noted, the term “alkylsulfanyl,” refers to the group —SR′ where R′ is an alkyl group as previously defined.
The term “oxo” refers to the group (═O).
Whenever the term “alkyl” or “aryl” or either of their prefix roots appear in a name of a substituent (e.g., arylalkyl, alkylamino) the name is to be interpreted as including those limitations given above for “alkyl” and “aryl.” Designated numbers of carbon atoms (e.g., C1-C6) refer independently to the number of carbon atoms in an alkyl moiety, an aryl moiety, or in the alkyl portion of a larger substituent in which alkyl appears as its prefix root. For alkyl and alkoxy substituents, the designated number of carbon atoms includes all of the independent members included within a given range specified. For example C1-6 alkyl would include methyl, ethyl, propyl, butyl, pentyl and hexyl individually as well as sub-combinations thereof (e.g. C1-2, C1-3, C1-4, C1-5, C2-6, C3-6, C4-6, C5-6, C2-5, etc.).
In general, under standard nomenclature rules used throughout this disclosure, the terminal portion of the designated side chain is described first followed by the adjacent functionality toward the point of attachment. Thus, for example, a “C1-C6 alkylcarbonyl” substituent refers to a group of the formula:

As used herein, the term “R” at a stereocenter designates that the stereocenter is purely of the R-configuration as defined in the art; likewise, the term “S” means that the stereocenter is purely of the S-configuration. As used herein, the terms “*R” or “*S” at a stereocenter are used to designate that the stereocenter is of pure but unknown configuration. As used herein, the term “RS” refers to a stereocenter that exists as a mixture of the R- and S-configurations. Similarly, the terms “*RS” or “*SR” refer to a stereocenter that exists as a mixture of the R- and S-configurations and is of unknown configuration relative to another stereocenter within the molecule.
Compounds containing one stereocenter drawn without a stereo bond designation are a mixture of two enantiomers. Compounds containing two stereocenters both drawn without stereo bond designations are a mixture of four diastereomers. Compounds with two stereocenters both labeled “RS” and drawn with stereo bond designations are a two-component mixture with relative stereochemistry as drawn. Compounds with two stereocenters both labeled “*RS” and drawn with stereo bond designations are a two-component mixture with relative stereochemistry unknown. Unlabeled stereocenters drawn without stereo bond designations are a mixture of the R- and S-configurations. For unlabeled stereocenters drawn with stereo bond designations, the absolute stereochemistry is as depicted.
Unless otherwise noted, it is intended that the definition of any substituent or variable at a particular location in a molecule be independent of its definitions elsewhere in that molecule. It is understood that substituents and substitution patterns on the compounds of formula (I) can be selected by one of ordinary skill in the art to provide compounds that are chemically stable and that can be readily synthesized by techniques known in the art as well as those methods set forth herein.

Embodiments of the present invention include prodrugs of compounds of formula (I). In general, such prodrugs will be functional derivatives of the compounds that are readily convertible in vivo into the required compound. Thus, in the methods of treating or preventing embodiments of the present invention, the term “administering” encompasses the treatment or prevention of the various diseases, conditions, syndromes and disorders described with the compound specifically disclosed or with a compound that may not be specifically disclosed, but which converts to the specified compound in vivo after administration to a patient. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.
Where the compounds according to embodiments of this invention have at least one chiral center, they may accordingly exist as enantiomers. Where the compounds possess two or more chiral centers, they may additionally exist as diastereomers. It is to be understood that all such isomers and mixtures thereof are encompassed within the scope of the present invention. Furthermore, some of the crystalline forms for the compounds may exist as polymorphs and as such are intended to be included in the present invention. In addition, some of the compounds may form solvates with water (i.e., hydrates) or common organic solvents, and such solvates are also intended to be encompassed within the scope of this invention. The skilled artisan will understand that the term compound as used herein, is meant to include solvated compounds of Formula I.
Where the processes for the preparation of the compounds according to certain embodiments of the invention give rise to mixture of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form, or individual enantiomers may be prepared either by enantiospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers by standard techniques, such as the formation of diastereomeric pairs by salt formation with an optically active acid, such as (−)-di-p-toluoyl-d-tartaric acid and/or (+)-di-p-toluoyl-1-tartaric acid followed by fractional crystallization and regeneration of the free base. The compounds may also be resolved by formation of diastereomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column.
One embodiment of the present invention is directed to a composition, including a pharmaceutical composition, comprising, consisting of, and/or consisting essentially of the (+)-enantiomer of a compound of formula (I) wherein said composition is substantially free from the (−)-isomer of said compound.

During any of the processes for preparation of the compounds of the various embodiments of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, Second Edition, J. F. W. McOmie, Plenum Press, 1973; T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991; and T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, Third Edition, John Wiley & Sons, 1999. The protecting groups may be removed at a convenient subsequent stage using methods known from the art.
Even though the compounds of embodiments of the present invention (including their pharmaceutically acceptable salts and pharmaceutically acceptable solvates) can be administered alone, they will generally be administered in admixture with a pharmaceutically acceptable carrier, a pharmaceutically acceptable excipient and/or a pharmaceutically acceptable diluent selected with regard to the intended route of administration and standard pharmaceutical or veterinary practice. Thus, particular embodiments of the present invention are directed to pharmaceutical and veterinary compositions comprising compounds of formula (I) and at least one pharmaceutically acceptable carrier, pharmaceutically acceptable excipient, and/or pharmaceutically acceptable diluent
By way of example, in the pharmaceutical compositions of embodiments of the present invention, the compounds of formula (I) may be admixed with any suitable binder(s), lubricant(s), suspending agent(s), coating agent(s), solubilizing agent(s), and combinations thereof.
Solid oral dosage forms, such as tablets or capsules, containing the compounds of the present invention may be administered in at least one dosage form at a time, as appropriate. It is also possible to administer the compounds in sustained release formulations.
Additional oral forms in which the present inventive compounds may be administered include exilirs, solutions, syrups, and suspensions; each optionally containing flavoring agents and coloring agents.
Alternatively, compounds of formula (I) can be administered by inhalation (intratracheal or intranasal) or in the form of a suppository or pessary, or they may be applied topically in the form of a lotion, solution, cream, ointment or dusting powder. For example, they can be incorporated into a cream comprising, consisting of, and/or consisting essentially of an aqueous emulsion of polyethylene glycols or liquid paraffin. They can also be incorporated, at a concentration of between about 1% and about 10% by weight of the cream, into an ointment comprising, consisting of, and/or consisting essentially of a white wax or white soft paraffin base together with any stabilizers and preservatives as may be required. An alternative means of administration includes transdermal administration by using a skin or transdermal patch.
The pharmaceutical compositions of the present invention (as well as the compounds of the present invention alone) can also be injected parenterally, for example intracavernosally, intravenously, intramuscularly, subcutaneously, intradermally or intrathecally. In this case, the compositions will also include at least one of a suitable carrier, a suitable excipient, and a suitable diluent.
For parenteral administration, the pharmaceutical compositions of the present invention are best used in the form of a sterile aqueous solution that may contain other substances, for example, enough salts and monosaccharides to make the solution isotonic with blood.
For buccal or sublingual administration, the pharmaceutical compositions of the present invention may be administered in the form of tablets or lozenges, which can be formulated in a conventional manner.
By way of further example, pharmaceutical compositions containing at least one of the compounds of formula (I) as the active ingredient can be prepared by mixing the compound(s) with a pharmaceutically acceptable carrier, a pharmaceutically acceptable diluent, and/or a pharmaceutically acceptable excipient according to conventional pharmaceutical compounding techniques. The carrier, excipient, and diluent may take a wide variety of forms depending upon the desired route of administration (e.g., oral, parenteral, etc.). Thus for liquid oral preparations, such as suspensions, syrups, elixirs and solutions, suitable carriers, excipients and diluents include water, glycols, oils, alcohols, flavoring agents, preservatives, stabilizers, coloring agents and the like; for solid oral preparations, such as powders, capsules and tablets, suitable carriers, excipients and diluents include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Solid oral preparations also may be optionally coated with substances, such as, sugars, or be enterically-coated so as to modulate the major site of absorption and disintegration. For parenteral administration, the carrier, excipient and diluent will usually include sterile water, and other ingredients may be added to increase solubility and preservation of the composition. Injectable suspensions or solutions may also be prepared utilizing aqueous carriers along with appropriate additives, such as solubilizers and preservatives.
A therapeutically effective amount of a compound of formula (I) or a pharmaceutical composition thereof includes a dose range from about 0.1 mg to about 3000 mg, in particular from about 1 mg to about 1000 mg or, more particularly, from about 10 mg to about 500 mg of active ingredient in a regimen of about 1 to 4 times per day for an average (70 kg) human; although, it is apparent to one skilled in the art that the therapeutically effective amount for active compounds of the invention will vary as will the diseases, syndromes, conditions, and disorders being treated.
For oral administration, a pharmaceutical composition is preferably provided in the form of tablets containing about 0.01, about 10, about 50, about 100, about 150, about 200, about 250, and about 500 milligrams of the inventive compound as the active ingredient.
Advantageously, a compound of formula (I) may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three and four times daily.
Optimal dosages of a compound of formula (I) to be administered may be readily determined and will vary with the particular compound used, the mode of administration, the strength of the preparation, and the advancement of the disease, syndrome, condition, or disorder. In addition, factors associated with the particular subject being treated, including subject age, weight, diet and time of administration, will result in the need to adjust the dose to achieve an appropriate therapeutic level. The above dosages are thus exemplary of the average case. There can be, of course, individual instances wherein higher or lower dosage ranges are merited, and such are within the scope of this invention.
Compounds of formula (I) may be administered in any of the foregoing compositions and dosage regimens or by means of those compositions and dosage regimens established in the art whenever use of a compound of formula (I) is required for a subject in need thereof.
As antagonists of the TRPM8 ion channel, the compounds of formula (I) are useful in methods for treating and preventing a disease, a syndrome, a condition, or a disorder in a subject, including an animal, a mammal and a human in which the disease, the syndrome, the condition, or the disorder is affected by the modulation of TRPM8 receptors. Such methods comprise, consist of, and consist essentially of administering to a subject, including an animal, a mammal, and a human in need of such treatment or prevention a therapeutically effective amount of a compound, salt, or solvate of formula (I). In particular, the compounds of formula (I) are useful for preventing or treating pain, or diseases, syndromes, conditions, or disorders causing such pain, or pulmonary or vascular dysfunction. More particularly, the compounds of formula (I) are useful for preventing or treating inflammatory pain, inflammatory hypersensitivity conditions, neuropathic pain, anxiety, depression, and cardiovascular disease aggravated by cold, including peripheral vascular disease, vascular hypertension, pulmonary hypertension, Raynaud's disease, and coronary artery disease, by administering to a subject in need thereof a therapeutically effective amount of a compound of formula (I).
Examples of inflammatory pain include pain due to a disease, condition, syndrome, disorder, or a pain state including inflammatory bowel disease, visceral pain, migraine, post operative pain, osteoarthritis, rheumatoid arthritis, back pain, lower back pain, joint pain, abdominal pain, chest pain, labor, musculoskeletal diseases, skin diseases, toothache, pyresis, burn, sunburn, snake bite, venomous snake bite, spider bite, insect sting, neurogenic bladder, interstitial cystitis, urinary tract infection, rhinitis, contact dermatitis/hypersensitivity, itch, eczema, pharyngitis, mucositis, enteritis, irritable bowel syndrome, cholecystitis, pancreatitis, postmastectomy pain syndrome, menstrual pain, endometriosis, sinus headache, tension headache, or arachnoiditis.
One type of inflammatory pain is inflammatory hyperalgesia, which can be further distinguished as inflammatory somatic hyperalgesia or inflammatory visceral hyperalgesia.

BIOLOGICAL EXAMPLES Example 1a In Vitro Canine TRPM8 Functional Assay
The functional activity of compounds of the formula (I) was determined by measuring changes in intracellular calcium concentration using a Ca2+-sensitive fluorescent dye. The changes in fluorescent signal were monitored by a fluorescence plate reader, either a FLIPR™ (Molecular Devices) or FDSS (Hamamatsu). Increases in intracellular Ca2+ concentration were readily detected upon activation with icilin.
At 24 hrs prior to assay, HEK293 cells stably expressing canine TRPM8 were seeded in culture medium in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR™ or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies. Curves were generated using the average of quadruplicate wells for each data point. The resultant data are displayed in Table 2.

Example 1b In Vitro Rat and Human TRPM8 Functional Assay
HEK293 cells are routinely grown as monolayer in Dulbecco's minimum essential medium supplemented with 10% FBS, 1 mM L-glutamine, 100 units/mL penicillin and 100 ug/mL streptomycin. Cells are maintained in 5% CO2 at 37° C.
For functional expression of TRPM8, the full-length cDNA encoding human and rat TRPM8 are subcloned into pCI-NEO mammalian expression vectors. The expression constructs are transiently transfected into HEK293 cells according to the FuGENE 6 transfection Reagent® (ROCHE) instructions. Within twenty-four hours, transiently transfected cells are harvested and either seeded directly into assay plate or cryopreserved for future usage.
Transfected cells may be either cryopreserved or freshly transfected and plated into clearbase poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) at a density of 10,000 cells per well in culture medium and grown overnight. The following day, all medium is removed and the cells are incubated with 52 μL of 0.5× Calcium 3 Dye (Molecular Devices) prepared in complete assay buffer containing 20 mM HEPES, 0.1% BSA, and 2.5 mM probenecid at 37° C. for thirty five minutes. The cells are then incubated for an additional fifteen minutes at room temperature before initiating experiments. Following incubation, plates are inserted into a FDSS instrument, where cells were challenged with compounds of the formula (I) (at varying concentrations) and intracellular Ca2+ are measured for 5 min prior to the addition of icilin at the EC80 concentration. IC50 values for compounds of the formula (I) are determined from eight point dose-response studies.
Maximal fluorescence intensity (FI) achieved upon addition of icilin is exported from the FDSS and further analyzed using GraphPad Prism 3.02 (Graph Pad Software Inc., CA, U.S.A.) where data is normalized to percent of maximal response. The dose response curves from the average of quadruplicate wells for each data point are analyzed by using nonlinear regression of either sigmoidal dose response or sigmoidal dose response (variable slope). Finally, the IC50 values are calculated with the best-fit dose curve determined by Prism. Results are shown in Table 3.

Example 2 TRPM8 Patch Clamp Assays
For patch clamp experiments, HEK293 cells are stably transfected with canine TRPM8 and cultured in DMEM supplemented with 10% fetal bovine serum, 100 units/ml penicillin, 100 μg/ml streptomycin and 1 mg/ml G418. Cells are maintained at 37° C. and in 5% CO2.
The extracellular solution contains (in mM): NaCl, 132; EGTA, 1; KCl, 5.4; MgCl2, 0.8; HEPES, 10; glucose, 10; pH=7.4. Recordings are performed using the conventional whole-cell patch clamp technique, 1-2 days after plating cells onto glass coverslips at densities appropriate for single cell recording. Currents are amplified by a patch clamp amplifier and filtered at 2 kHz (Axopatch 200B, Molecular Devices, Union City, Calif.). Menthol (100 μM) is applied to the cell at 0.5 ml/min via a gravity-fed perfusion system. Recordings involving menthol activation are performed at 22° C.
In experiments where temperatures are varied, temperature ramps are generated by cooling the perfusate in an in-line cooler (Model SC-20, Warner Instruments, Hamden, Conn.) controlled by a temperature controller (Model CL-100, Warner Instruments). The temperature in the vicinity of the recorded cell is measured with a custom-made miniature thermo-microprobe connected to a monitoring thermometer (Model TH-8, Physitemp, Clifton, N.J.), and sampled using Digidata 1322A and pClamp 9.0 (Molecular Devices), as are the currents concurrently measured in the whole-cell patch clamp mode. The current is continuously sampled (at 100 Hz) at a holding potential of −60 mV.
Compounds of the formula (I) are diluted from 10 mM DMSO stocks (stored at −20° C.) into an extracellular solution either containing 100 μM menthol or subjected to cooling. Increasing concentrations of a compound are applied to a cell in a cumulative manner and concentration-dependent responses are measured after steady-state activation is achieved by either 100 μM menthol or cooling to 10° C. A saturating concentration of a reference antagonist is applied at the end of an experiment (either in the presence of 100 μM menthol or 10° C. temperature) to establish the baseline from which all the other measurements are subtracted.
Percentage inhibition by a compound is calculated as follows:
100×(1−Icomp/I0);
where Icomp and I0 are steady-state current amplitudes in either the presence or absence of a concentration of compounds of the formula (I). Concentration-response data are fitted to a logistic function as follows: R=100/(I+c/IC50)p; where, R is the percentage inhibition, p is the Hill coefficient and c is the concentration of compounds of the formula (I). Results are shown in Table 4.

In Vivo Models Example 3 Inhibition of Icilin-induced Behaviors in Rodents
Icilin was initially developed as a “super-cooling” compound by Delmar Chemicals Ltd. Subsequently it was shown to be one of the most potent known agonists of TRPM8 (McKemy D D, et al. Nature 2002, 416(6876): 52-8), having an EC50=0.2 μM in stimulating calcium ion influx into TRPM8 transfected cells (Behrendt H J et al. Brit J Pharmacol 2004, 141(4): 737-45). Initial in vivo testing of icilin showed it to cause “wet-dog” shakes in rats. Similar shaking or jumping behavior was also evident in mice, rabbits, cats, dogs and monkeys. In humans, icilin produced a sensation of coolness on contact with mucous membranes, cold prickling when 0.1 mg was dropped on the tongue and coldness in the mouth, pharynx and chest lasting 30-60 minutes when 5-10 mg was ingested orally (Wei E T, Seid D A, J Pharm Pharmacol. 1983, 35, 110). The inhibition or reversal of icilin-induced shaking behaviors in rodents provides evidence for the utility of TRPM8 antagonists of the formula (I) in treating or preventing a disease, syndrome, disorder, or condition in a subject in which the disease, syndrome, disorder or condition is affected by the modulation of TRPM8 receptors.
Example 3a Inhibition of Icilin-induced “Wet-Dog” Shakes in Rats
Male Sprague Dawley rats (220-450 g, Charles River Labs, n=6-9/treatment) were used to evaluate the ability of selected compounds of the formula (I) to block icilin-induced “wet-dog” shakes (WDS). Compounds of the formula (I) were administered in an appropriate vehicle, such as hydroxypropyl-β-cyclodextrin (HPβCD), methocellulose, 10% Solutol, or H2O, or the like, by the appropriate route, i.p. or p.o., 30-120 minutes before icilin. Icilin was administered in PEG-400 or 10% solutol/H2O, at 1.0 or 3.0 mg/kg, i.p. and spontaneous “wet-dog” shakes were counted 10-20 minutes post-icilin. Results are presented as a percent inhibition of shakes, which was calculated as [1−(test compound WDS count/vehicle WDS count)]×100. Results are shown in Table 5.

Example 3b Reversal of Icilin-induced Behaviors in Rats
Male Sprague Dawley rats (225-450 g, Charles River Labs, n=4-6/treatment) were used to evaluate the ability of selected compounds of the formula (I) to reverse icilin-induced “wet-dog” shakes. Icilin was administered in PEG-400 or 10% solutol/H2O, at 1.0 or 3.0 mg/kg, i.p. and spontaneous “wet-dog” shakes (WDS) were counted 10-20 minutes post-icilin. Animals that exhibited 10 or more shakes were randomized into treatment groups and immediately administered compounds of the formula (I) in an appropriate vehicle, such as hydroxypropyl-β-cyclodextrin (HP βCD), methocellulose, 10% Solutol, or H2O, or the like, and by the appropriate route, such as i.p. or p.o. Spontaneous “wet-dog” shakes were counted 60-70 minutes after compound administration. Results are presented as a percent inhibition of shakes, which was calculated as [1−(test compound WDS count/vehicle WDS count)]×100. Results are shown in Table 6.

Example 3c Rightward Shift of Icilin Dose Effect Curve in Rats
Male Sprague Dawley rats (200-400 g, Charles River Labs, n=6-9/treatment) were administered icilin in a suitable vehicle (e.g. PEG-400, 10% Solutol) at 0.1-30 mg/kg, i.p. Spontaneous “wet-dog” shakes were counted 10-20 minutes post-icilin in order to generate a icilin dose-effect curve. A compound of the present invention was administered orally in hydroxypropyl-β-cyclodextrin 60 minutes before icilin challenge to assess the compound's ability to inhibit spontaneous “wet-dog” shakes (WDS) produced by a range of icilin doses. The ED50 of the icilin dose-effect curve generated in the presence of TRPM8 antagonist may be compared to that generated in the presence of vehicle to determine the magnitude of rightward shift as shown below in Table 7.

Example 4 In Vivo Model of Subacute Inflammatory Pain: Carrageenan-induced Hyperalgesia
Intraplantar injection of carrageenan into the hind paw of rats causes a robust acute inflammatory response characterized by reddening, swelling and hypersensitivity of the paw to thermal and mechanical stimuli typically peaking 3-6 hours following application and subsiding over the 12-24 hours.
Example 4a Rat Carrageenan-induced Radiant Heat Hypersensitivity
To assess the effect of test compounds of the formula (I) on inflammatory hyperalgesia radiant heat response latencies were evaluated 3 hours following intraplantar carrageenan (Lambda, Type IV, 200 uL) injection into a single hind paw in male Sprague-Dawley rats. The test compound was administered either 2 hours prior to or 1 hour following carrageenan injection. The intent was to determine whether the compound would prevent or retard the hypersensitivity associated with this inflammogen. Baseline thermal response latencies were determined prior to any treatment and again 3 hours after carrageenan injection. Percent reversal of hyperalgesia relative to vehicle treatment (% R) was calculated for both compound treatment paradigms according to the following formula and is depicted in Table 8:
% R=(Post compound latency−Post vehicle latency)/((Baseline latency−Post vehicle latency)×100%

Example 5 In Vivo Model for of Chronic Inflammatory Pain: Complete Freund's Adjuvant (CFA)-induced Hyperalgesia
Intraplantar injection of complete Freund's adjuvant (CFA) in rodents results in a long-lasting inflammatory reaction, characterized by a pronounced hypersensitivity to both thermal and mechanical stimuli. This hypersensitivity peaks between 24-72 hours following injection and can last for several weeks. To assess whether test compounds of the formula (I) reverse established hypersensitivity, a 100 μL intraplantar injection of CFA (suspended in a 1:1 emulsion of saline and heat-killed Mycobacterium tuberculosis in mineral oil) can be injected into a single hind paw of Sprague-Dawley rats (typically males ranging from 150-350 g). This paradigm also may be conducted with a multiple dosing or a prophylactic dosing regime designed to alter the course of hyperalgesia development. This test predicts the analgesic, anti-allodynic and antihyperalgesic effect of numerous effective clinical agents, including acetaminophen, NSAIDS such as aspirin and ibuprofen, and opioids, such as morphine.
Example 5a CFA-induced Paw Radiant Heat Hypersensitivity
Each rat is placed in a test chamber on a warm glass surface and allowed to acclimate for approximately 10 minutes. A radiant thermal stimulus (beam of light) is then focused through the glass onto the plantar surface of each hind paw in turn. The thermal stimulus is automatically shut off by a photoelectric relay when the paw is moved or when the cut-off time is reached (20 seconds for radiant heat at ˜5 Amps). An initial (baseline) response latency to the thermal stimulus is recorded for each animal prior to the injection of CFA. Twenty-four hours following intraplantar CFA injection, the response latency of the animal to the thermal stimulus is then re-evaluated and compared to the animal's baseline response time. Only rats that exhibit at least a 25% reduction in response latency (i.e. hyperalgesia) are included in further analysis. Immediately following the post-CFA latency assessment, test compound or vehicle (usually Solutol, hydroxypropyl methylcellulose, hydroxypropyl beta-cyclodextrin or PEG-400) is administered i.p. or p.o. to rats. Post-compound treatment withdrawal latencies are assessed at fixed time intervals, typically 30, 60 and 120 minutes. The percent reversal (% R) of hypersenstivitiy is calculated according to the following formula:
% Reversal=(Treatment Response-CFA Response)/(Baseline Response-CFA Response)×100.

Example 5b CFA-induced Paw Cold Hypersensitivity
Prior to intraplantar CFA injection, mice or rats are placed individually in elevated observation chambers having wire mesh floors. Through the mesh floor a series of three applications of acetone (0.04-0.10 mL/application) is sprayed onto the bottom of the paw using a multidose syringe device. A positive response takes the form of an abrupt withdrawal and licking of the paw. The cumulative duration of licking is recorded for each of the three trials which are then averaged to give the individual's response. Twenty-four hours following CFA injection acetone licking durations are markedly elevated implying a hypersensitivity to cooling. Test compounds of the formula (I) can be assessed for its ability to return acetone-evoked paw licking durations to pre-CFA levels (typically near zero) following systemic administration. Percent inhibition is calculated as follows
% Inhibition=[1−(treatment licking duration/vehicle licking duration)]×10.
Example 6 Chemically-induced Abdominal Irritant Models of Visceral Pain
A chemical irritant (such as acetic acid, kaolin, bradykinin, phenyl-p-(benzo) quinine, bromo-acetylcholine, or zymosan) is injected in mice intraperitoneally, causing a contraction of the abdominal musculature, which is characterized by an elongation of the body extending through to the hind limbs. The number of such responses is quantitated and is reduced by pretreatment of analgesic agents, thus forming the basis for a screening test (Collier H O et al. Br J Pharmacol Chemother 1968, 32(2): 295-310). This type of abdominal irritant test has been used to predict the analgesic effect of numerous clinically effective agents, the potency of which in the abdominal irritant test parallels the magnitude of the dose needed in the relief of clinical pain. Such agents include acetaminophen, NSAIDS such as aspirin and ibuprofen, opioids, such as morphine and codeine, and other centrally acting analgesics, such as tramadol.
One modification of the chemically-induced abdmonial irritant model of visceral pain is to pretreat animals with agents known to induce inflammatory responses following intraperitoneal injection (such as LPS, zymosan, or thioglycolate). A small intraperitoneal dose of such an inflammogen, administered hours or days before the acute chemical irritant challenge, has been shown to increase the number of abdominal contractions observed (Ribeiro R A, et al. Eur J Pharmacol 2000, 387(1): 111-8). While some analgesic agents are effective at mitigating acute viscerochemical nociception, others, particularly those dependent upon receptor induction are more effective at preventing or reversing the enhancement of behavioral responses caused by a preconditioning inflammatory stimulus. Because of the up-regulation of the TRPM8 receptor in inflammation, TRPM8 antagonists that are effective at reducing the mean number of contractions are predicted to provide analgesic action in human clinical use.
The ability of compounds of the formula (I) to mitigate chemical irritant—induced abdominal contractions following a pre-conditioning inflammatory stimulus can be studied as follows. Thioglycolate (3%, w/v, 2-3 mL i.p.) is injected into male CD1 mice (20-40 g, Charles River Labs), at a maximum dosage volume of 80 mL/kg, to induce peritoneal inflammation. Following a twenty-four hour pre-inflammation period these mice are dosed orally with compounds of the formula (I) (30 mg/kg; n=10) or vehicle (HPMC with 2% Tween80; n=9) and then one hour later subjected to an abdominal irritant challenge of acetic acid (1%, 10 mL/kg, i.p.). Immediately following injection of acetic acid, mice are placed individually in glass bell jars (approximately 15 cm in diameter) for counting of abdominal contractions over the next 15 minutes. The total number of abdominal contractions is summed for each treatment group and employed in the following formula to calculate Percent Inhibition (% I):
% I=[1−(test compound contractions/vehicle contractions)]×100.
Example 7 In Vivo Models of Neuropathic Pain
The sciatic nerve is the major sensorimotor innervation of the (hind) leg and foot. Injury to the sciatic nerve or its constituent spinal nerves often results in pain-related behaviors. In rats and mice, tight ligation of the L5 spinal nerve with silk suture, partial tight ligation of the sciatic nerve with silk suture or loose ligation of the sciatic nerve with chromic gut suture each result in behaviors reminiscent of neuropathic pain in humans. These lesions (one per animal) are performed surgically in anesthetized rodents. Both the spinal nerve and sciatic nerve lesions result in allodynia, a painful response to normally innocuous stimuli, and hyperalgesia, an exaggerated response to normally noxious stimuli. It is important to note that both of these pain-related behaviors are evoked by the testing procedures and that normal use of the paw (e.g., walking) is relatively uncompromised, apart from occasional “guarding” of the paw. Subsequent to the surgery, the subjects' behaviors, such as grooming, feeding, and weight gain, are normal, except for hypersensitivity (as defined above) of the affected paw.
In addition to induction by nerve damage resulting from accidental trauma or surgical procedures, neuropathic pain can also be induced by diabetes (Fox, A et al., Pain 81:307-316, 1999) or by treatment with chemotherapeutic agents, such as paclitaxel or vincristine (Yaksh, T L et al., Pain 93:69-76, 2001).
Agents that attenuate neuropathic pain in the clinic also are effective in rodent neuropathic pain models. These agents include the recently approved Cymbalta (Duloxetine, lyengar, S., et al., JPET 2004 311:576-584), morphine (Suzuki, R et al., Pain 1999 80:215-228) and gabapentin (Hunter, J C et al., Eur J Pharmacol 1997 324:153-160). The dual TRPV1/TRPM8 receptor antagonist BCTC reduced mechanical hyperalgesia and tactile allodynia in the chronic constriction injury rodent neuropathic pain model (Pomonis, J D et al., JPET 2003 306:387-393; Behrendt, H et al., Brit J Pharm 2004 141:737). Cold allodynia is a particularly debilitating symptom of neuropathic pain conditions (Jorum E et al. Pain 2003 101: 229-235). The antiallodynic effect of compounds of the formula (I) in this rodent model is predictive of clinical effect for these novel agents.
Example 7a Chronic Constriction Injury (CCI)-induced Model of Neuropathic Pain Acetone-induced Hypersensitivity
Male Sprague Dawley rats (225-450 g; n=5-8/treatment) were used to evaluate the ability of selected compounds of the formula (I) to reverse CCI-induced cold hypersensitivity. Four loose ligatures of 4-0 chromic gut were surgically placed around the left sciatic nerve under inhalation anesthesia as described by Bennett et al (Bennett G J, Xie Y K. Pain 1988, 33(1): 87-107). Fourteen to 35 days following CCI surgery, subjects were placed in elevated observation chambers containing wire mesh floors and five applications of acetone (0.05 mL/application separated by approximately 5 minutes) were spritzed onto the plantar surface of the paw using a multidose syringe. An abrupt withdrawal or lifting of the paw was considered a positive response. The number of positive responses was recorded for each rat over the five trials. Following baseline withdrawal determinations, compounds of formula (I) are administered in an appropriate vehicle, such as hydroxypropyl-β-cyclodextrin (HP β CD), methylcellulose, Methocel, 10% Solutol, or H2O, or the like, by the appropriate route, i.p. or p.o. The number of withdrawals were redetermined 1 to 3 h after compound administration. Results are presented as a percent inhibition of shakes, which was calculated for each subject as [1−(test compound withdrawals/pre-test withdrawals)]×100 and then averaged by treatment. Results are shown in Table 10.

Example 7b Chronic Constriction Injury (CCI)-induced Model of Neuropathic Pain—Cold Plate-induced Hypersensitivity
In male SD rats (175-325 g), four loose ligatures of 4-0 chromic gut are surgically placed around the left sciatic nerve under inhalation anesthesia as described by Bennet et al (Bennett G J, Xie Y K. Pain 1988, 33(1): 87-107). Seven to 21 days following sciatic chronic constriction injury (CCI) surgery, the subjects can be placed onto a commercial cold plate device cooled by peltier elements such that the surface temperature is held at 1° C. Each subject can undergo a 6 minute conditioning period followed by a 3 minute assessment period during which the total duration of hind paw lifting is recorded. This procedure is repeated at several intervals prior to and following systemic drug administration. Compounds of the formula (I) can be assessed for their ability to return duration of paw lifting back to pre-lesion levels. The duration of paw lifting during the 3 minute test period following administration of test compound is taken as a percentage of the duration of paw lifting during the 3 minute test period prior to test compound treatment.
Example 7c Chronic Constriction Injury (CCI)-induced Model of Neuropathic Pain—Mechanical Allodynia (Von Frey Test)
In male SD rats (175-325 g), four loose ligatures of 4-0 chromic gut are surgically placed around the left sciatic nerve under inhalation anesthesia as described by Bennet et al (Bennett G J, Xie Y K. Pain 1988, 33(1): 87-107). Seven to 21 days following sciatic chronic constriction injury (CCI) surgery, the subjects can be placed onto an elevated rack of plexigas chambers having wire mesh or another type of perforated flooring. The measurement of mechanical allodynia can be performed using the von Frey hairs (Semmes-Weinstein Monofilaments, Stoelting Co., IL) wherein the rats can be habituated to the wire mesh bottom cages before the start of the experiment. Static allodynia can be tested in the unrestrained rats by touching the plantar surface of the hind paw with von Frey hairs in ascending order of force (1.2, 1.5, 2.0, 3.6, 5.5, 8.5, 12, 15, 29, and 76 g) for up to 6 s or until a paw withdrawal response can be elicited. The lowest amount of force required to elicit a response can be recorded as the withdrawal threshold in log g. This procedure is repeated at several intervals prior to and following systemic drug administration. Compounds of the formula (I) can be assessed for their ability to return the threshold force which elicits paw lifting back to pre-lesion levels.
Example 8 Inflammatory Agent-induced Models of Pyresis/Antipyresis
Compounds of the formula (I) can be tested in animal models of pyresis, according to previously documented and validated methods, such as those described by Kozak et al (Kozak W, Fraifeld V. Front Biosci 2004, 9: 3339-55). Fever is a frequent accompaniment of inflammatory disease. Animal models make use of the pyretic properties of yeast and other inflammatory agents, injecting a yeast suspension or other agent subcutaneously (Tomazetti J et al. J Neurosci Methods 2005, 147(1): 29-35); Van Miert A S, Van Duin C T. Eur J Pharmacol 1977, 44(3): 197-204). For example, Male Wistar rats (75-100 g) can be housed in groups of four to a cage at controlled temperature (23±1° C.) with a 12 h light: 12 h dark cycle (lights on at 07:00 h) and with standard lab chow and tap water ad libitum. All measured temperatures can be taken between 08:00 and 19:00 h. Each animal can be used in only one study. Rectal temperature (TR) can be measured by inserting a lubricated thermistor probe (external diameter: 3 mm) 2.8 cm into the rectum of the animal. The probe can be linked to a digital device, which displayed the temperature at the tip of the probe with a 0.1° C. precision and logs the values over time. Immediately after measuring the initial basal rectal temperature, the animals can be injected with commercially available dried baker yeast (Saccharomyces cerevisiae) suspended in pyrogen-free 0.9% NaCl (0.05-0.25 g/kg, i.p.) or 0.9% NaCl (10 ml/kg). TR changes can be recorded every hour up to 12 h, and expressed as the difference from the basal value. Since it has been previously reported that handling and temperature measuring-related stress alter rectal temperature, these animals can be habituated to the injection and measuring procedure for 2 days before experiments are carried out. In these sessions, the animals can be subjected to the same temperature measuring procedure described above, and can be injected intraperitoneally (i.p.) with 0.9% NaCl (10 ml/kg).
To assess the effect of potential antipyretic compounds on basal rectal temperature study animals can have their TR measured for 4 h, and after the fourth TR measurement they can be subcutaneously (s.c.) injected with vehicle (such as 10% Solutol in sterile water 5 ml/kg) or compounds of the formula (I) prepared in vehicle. TR can then be recorded every hour up to 8 h after the compound injections. To assess the effect of compounds of the formula (I) on baker yeast-induced hyperthermia, study animals can have their basal TR measured and then be injected with a pyrogenic dose of baker yeast (for example, 0.135 g/kg). TR changes can be recorded every hour up to 4 h, when potential antipyretics agents such as those compounds of the formula (I) are administered. Rectal temperature can then be monitored over the following 8 h. Basal rectal temperature and changes in rectal temperature can be expressed as means±S.E.M. of the differences from TR at 07:00 h. Data can be analyzed by two-way analysis of variance (ANOVA), with time of measures treated as within subject factor, depending on the experimental design. Post hoc analysis can be carried out by the F-test for simple effect and the Student-Newman-Keuls test, when appropriate. A value of P<0.05 would be considered statistically significant.
The modification of the subsequent pyretic response by therapeutic agents can also be monitored by rectal telemetry or other measurements of body temperature. Several clinically relevant agents such as acetaminophen, aspirin and ibuprofen, reduce fever in these models. The antipyretic effect of TRPM8 antagonists, such as compounds of the formula (I), in these tests would also be predictive of their clinical effect.
Example 9 CFA-induced Model of Rheumatoid Arthritis
Compounds of the formula (I) can be tested in animal models of rheumatoid arthritis, according to previously documented and validated methods, such as those described by Nagakura et al (Nagakura Y, et al. J Pharmacol Exp Ther 2003, 306(2): 490-7). For example, arthritis can be induced by the CFA inoculation in the rats (Male Lewis rats 150-225 g; Charles River). Briefly, 100 mg of Mycobacterium butyricum (Difco, Detroit, Mich.) can be thoroughly mixed with 20 mL of paraffin oil. Then mixture can be autoclaved for 20 min at 120° C. Each rat can be injected in the right footpad (hind paw) with the mixture in a 0.1-mL volume under inhalation anesthesia. The rats serving as controls can be injected with 0.1 mL of saline. Pain and other disease development parameters can be measured in the CFA- or saline-treated rats just before inoculation and up to 28 days post-inoculation. The measurement for pain parameters can be conducted for both mechanical and thermal (hot or cold) endpoints. The measurement of mechanical allodynia can be performed using the von Frey hairs (Semmes-Weinstein Monofilaments, Stoelting Co., IL) wherein the rats can be habituated to wire mesh bottom cages before the start of the experiment. Static allodynia can be tested in the unrestrained rats by touching the plantar surface of the hind paw with von Frey hairs in ascending order of force (1.2, 1.5, 2.0, 3.6, 5.5, 8.5, 12, 15, 29, and 76 g) for up to 6 s or until a paw withdrawal response can be elicited. The lowest amount of force required to elicit a response can be recorded as the withdrawal threshold in log g. Thermal hyperalgesia can be assessed using the radiant heat test wherein a mobile radiant heat source can be located under a glass surface upon which the rat is placed. The beam of light can be focused on the hind paw, and the paw withdrawal latencies are defined as the time taken by the rat to remove its hind paw from the heat source. The measurement of joint hyperalgesia can be performed by a modification of the previously reported method (Rupniak N M J et al. Pain 1997, 71: 89-97). The torso of each rat can be held from the back with the left palm, and the bending and extension (one after the other and five times in each direction) of the ankle within its limits of range of motion can be performed with the right fingers. The total number of vocalizations emitted after the manipulation (the bending and extension, five times in each direction) can be recorded for each paw (the maximum score is 10 for each paw).
The scoring of mobility can be performed by modifying the evaluation scale reported by Butler et al. (Butler S H et al Pain 1992, 48: 73-81): score 6, walks normally; score 5, walks being protective toward the ipsilateral hind paw (touches the ipsilateral hind paw fully on the floor); score 4, walks being protective toward the ipsilateral hind paw (touches only the toe of the ipsilateral hind paw on the floor); score 3, walks being protective toward both hind paws (touches the contralateral hind paw fully on the floor); score 2, walks being protective toward both hind paws (touches only the toe of the contralateral hind paw on the floor); score 1, crawls only using the fore paws; and score 0, does not move. Paw volumes can be measured by volume displacement of electrolyte solution in a commercially available plethysmometer device. The hind paw can be immersed to the junction of the hairy skin, and the volumes can be read on a digital display. The scoring of joint stiffness can be performed as follows: the body of rats can be held from the back with the left palm, and the bending and extension (once in each direction) of the ankle within its limits of range of motion can be performed with the right fingers. It can be confirmed beforehand that there is no restriction of ankle joint movement in the bending and extension manipulations in naive rats, and the scoring can be performed according to the evaluation scale reported by Butler (Butler S H et al Pain 1992, 48: 73-81): score 2, there are restrictions of full range of movement of the ankle in both bending and extension; score 1, there is a restriction of full range of movement of the ankle in bending or extension; and score 0, no restriction. The measurements for paw volume and joint stiffness can be conducted for both hind paws.
Compounds of the formula (I) can be assessed for antihyperalgesic efficacy as follows: thirty-two rats (8 rats per dose and four doses per compound) that are be treated with the CFA and another eight rats as naive controls can be used for each drug evaluation. The analgesic effects can be evaluated on post-inoculation day 9, when mechanical allodynia, thermal hyperalgesia, joint hyperalgesia, and joint stiffness in the ipsilateral paw reached almost the maximum, although those parameters in the contralateral paw changed only slightly and the systemic disturbance shown by the change of mobility score is small. On the day before evaluation, body weight, mechanical allodynia, thermal hyperalgesia, and joint hyperalgesia can be measured for the 32 rats that are to be used for compound evaluation. The rats are allocated to four groups (eight rats per group) such that the differences in the averages of those parameters among the groups became small. All the analgesic effect evaluations and behavioral observations can be carried out by the observer who is blind to the drug treatment.
Data can be expressed as the mean+/−S.E.M. The time-course curves for mechanical allodynia, thermal hyperalgesia, joint hyperalgesia, body weight, and paw volume can be subjected to two-way repeated measures analysis of variance with post hoc t test. In experiments for evaluation of compounds of formula (I), the difference in scores between the vehicle-treated and naive control groups can be analyzed by Student's t test to confirm significant changes in the pain parameters in the ipsilateral paw. The analgesic effects can be analyzed by Dunnett's t test, and in each case the drug-treated groups can be compared with the vehicle-treated group. In each statistical analysis, the comparison can be conducted for paws on the corresponding side. P<0.05 is considered statistically significant. In this model, the centrally acting analgesics morphine and tramadol fully relieved pain, whereas the NSAIDs, indomethacin and diclofenac are partially effective, evidencing the model's clinical predictability. The analgesic effect of compounds of the formula (I) in this test would predict their clinical usefulness in treating arthritis.
Example 10 In vivo Model for Arthritis: Inflammogen-induced Hyperalgesia of the Knee Joint
Compounds of the formula (I) can be tested in animal models of osteoarthritis, according to previously documented and validated methods, such as those described by Sluka et al (Sluka K A, Westlund K N. Pain 1993, 55(3): 367-77). For example, male Sprague-Dawley rats (Harlan, Indianapolis, Ind.) weighing 225 to 350 g can be briefly anesthetized with vaporized halothane and then injected with a mixture of 3% carrageenan and 3% kaolin (100 μL in 0.9% sterile saline) into the joint cavity of one knee. After the injection, the animals can be returned to their cages until the time of testing. For behavioral testing animals can be placed in individual clear plastic cages on top of an elevated wire mesh surface that restricted movement. The animals should be allowed to acclimate for approximately 1 hour before testing. Von Frey filaments, as described above, can then be used to test for enhanced responses to mechanical stimuli. The filaments can be successively applied through the wire mesh perpendicularly to the plantar surface in between the pads of the third and fourth phalanges. The response threshold to mechanical stimuli can be determined before inflammation of the knee joint; 4 hours after inflammation to confirm the development of hyperalgesia; immediately after the administration of test compound such as those of Formula (I) i.e. 5 hours after inflammation; and at 8, 12, and 24 hours after inflammation.
The Kruskal-Wallis test, a nonparametric test, can be used to analyze the effects for frequency, intensity, and group for response to mechanical stimuli at baseline, 4 hours after inflammation, and after compound treatment (5 hours, 8 hours, 12 hours, and 24 hours after inflammation). Further post hoc testing between groups can be executed by using the Mann-Whitney signed rank test. The data can be presented as median with 25th and 75th percentiles. Significance is P≦0.05.
Additionally, the gait of the animal or other pain-related behavior can be scored as the dependent measure of the painful effect of the arthritis on the animal's activity (Hallas B, Lehman S, Bosak A, et al. J Am Osteopath Assoc 1997, 97(4): 207-14). The effect of test drug on the animal's normal behavior can be quantified from zero, meaning no response, to three for incapacitating impairment. Effective analgesic treatment includes the clinically used indomethacin (Motta A F, et al. Life Sci 2003, 73(15): 1995-2004). Thus the benefit of compounds of the formula (I) in this model would predict their clinical relevance.
Example 11 Sarcoma Cell-induced Models of Bone Cancer Pain
Compounds of the formula (I) can be tested in animal models of bone cancer pain, according to previously documented and validated methods, such as those described in the scientific literature (El Mouedden M, Meert T F. Pharmacol Biochem Behav 2005, 82(1): 109-19; Ghilardi J R, et al. J Neurosci 2005, 25(12): 3126-31). In preparation for cell inoculation and tumor induction, osteolytic murine sarcoma cells (NCTC 2472, American Type Culture Collection (ATCC), Rockville, Md., USA) can be cultured in NCTC 135 medium (Invitrogen) containing 10% horse serum (Gibco) and passaged 2 times weekly according to ATCC guidelines. For their administration, cells can be detached by scraping and then centrifuged at 1000×g. The pellet can be suspended in fresh NCTC 135 medium (2.5×106 cells/20 μL) and then used for intramedullary femur inoculation. Male C3H/HeNCrl mice (25-30 g, Charles River Labs) can be used in such experiments. After induction of general anesthesia with xylazine (10 mg/kg i.p.) and ketamine (100 mg/kg i.p.) the left hind paw can be shaved and disinfected with povidone-iodine followed by 70% ethanol. A superficial incision of 1 cm can then be made over the knee overlaying the patella. The patellar ligament can then be cut, exposing the condyles of the distal femur. A 23-gauge needle can be inserted at the level of the intercondylar notch and the intramedullary canal of the femur to create a cavity for injection of the cells. Twenty microliters of media (sham animals) or media containing tumor cells (approximately 2.5×106 cells) can then be injected into the bone cavity using a syringe. To prevent leakage of cells outside the bone, the injection site can be sealed with dental acrylic and the wound closed with skin stitches.
Pain behaviors can be evaluated in separate groups (n=6) of sham and bone tumor mice with confirmed hyperalgesia as assessed by spontaneous lifting behavior. Animals can be behaviorally tested during a 3-week period prior to and after tumor inoculation. Body weight of the mice can be recorded throughout the experimental period to help monitor general health status. To measure the spontaneous lifting, the animals can be habituated in a transparent acrylic cylinder of 20 cm diameter put on an horizontal surface and thereafter observed during 4 min for spontaneous lifting behavior of the left hind paw. After spontaneous lifting behavior assessment, animals can be immediately placed on a mouse rotarod (e.g. ENV-575M, Med Associates Inc., GA, USA) at a speed of 16 rpm for 2 min wherein limb-use during forced ambulation is scored: 4=normal; 3=limping; 2=partial non-use of left hind paw; 1=substantial non-use of left hind paw; 0=non-use of left hind paw. Assessment of cold allodynia may be made by exposing the ipsilateral hind paw of the mouse to 5 repeated applications of acetone (20 μL) and quantifying the lift/licking frequency and/or duration. Post-mortem evaluation of bone destruction can be assessed by ACT processing followed by scanning using a system such as the Skyscan 1076 microtomograph system for small animal imaging (Skyscan 1076\, Skyscan, Aartselaar, Belgium). Measured histomorphometry parameters of bone destruction can be subsequently correlated with behavioral endpoints.
The antihyperalgesic, antiallodynic and disease modifying effects of compounds of the formula (I) can be tested in this murine model of bone cancer pain in separate groups (n=6 per dose group). Animals with confirmed hyperalgesia, as assessed by spontaneous or acetone-evoked lifting, can be behaviorally tested, for example, on days 15 and 22 after distal femur tumor inoculation before and 1 h after systemic administration of vehicle (e.g. 20% HPbCD in sterile water) or compounds of the formula (I). The statistical analysis can be performed by one-way ANOVA to compare behavioral measurements and bone parameters among the experimental groups. To compare behavioral measurements and bone parameters between sham and tumor-bearing animals, a Mann-Whitney U test can be used. Results are considered statistically significant at P<0.05 (two-tailed). Data are expressed as mean+/−S.E.M.
Bone cancer causes intense pain in humans, mimicked in animal models of bone cancer pain in rodents such as that described above. Analgesic treatments that are effective in this model include COX-2 inhibitors (Sabino M A, Ghilardi J R, Jongen J L, et al. Cancer Res 2002, 62(24): 7343-9) and high doses of morphine (Luger N M et al. Pain 2002, 99(3): 397-406), agents used clinically for pain relief in patients experiencing bone cancer pain. Because this model so closely mimics the human disease state, the finding that cold allodynia is a prominent symptom (Lee, Seong et al. Yonsei Med J 2005, 46(2): 252-9) strongly supports the concept that TRPM8 antagonists of the present invention will provide relief of pain associated with human bone cancer.
Example 12 Respiratory Irritant-induced Models of Cough
Compounds of the formula (I) can be tested in animal models of antitussive activity, according to previously documented and validated methods, such as those described by: Tanaka, M. and Maruyama, K. J Pharmacol. Sci 2005, 99(1), 77-82; Trevisani, M. et al., Throax 2004, 59(9), 769-72; and Hall, E. et al., J Med. Microbiol 1999, 48: 95-98. Testing is conducted in transparent ventilated chambers with a constant airflow of 400 mL/min. The tussive agent (citric acid 0.25 M or capsaicin 30 mM) can be nebulised via a miniultrasonic nebuliser with an output of 0.4 mL/min. The appearance of cough can be detected by means of a tie clip microphone and confirmed by the characteristic posture of the animal. The cough sounds can be recorded and digitally stored. A blinded observer subsequently counts the number of elicited cough efforts. In some cases, animals can be sensitized by pre-exposure to certain agents such as ovalbumin. A test compound can be administered to at the peak of irritant-induced cough to evaluate the antitussive effects of the compound. In addition, prophylactic or multiple dosing regimes can be utilized to evaluate the test compound for modulation of the onset and duration of irritant-induced cough. Variations of these tests predict the antitussive effects of effective clinical agents, including NMDA antagonists such as dextrorphan and dextromethorphan, opioids such as codeine, beta 2 agonists such as salbutamol and antimuscarinics such as ipratropium (Bolser, D. C. et al., Eur J Pharmacol 1995, 277(2-3), 159-64; Braga, P. C. Drugs Exper Clin Res 1994, 20, 199-203). The antitussive action of menthol in both guinea pig and humans Eccles R. Curr Allergy Asthma Rep 2003, 3(3): 210-4; Laude E A, et al. Pulm Pharmacol 1994, 7(3): 179-84; Morice A H, et al. Thorax 1994, 49(10): 1024-6) is predictive of the clinical utility of compounds of the formula (I) as antitussive agents.
Example 13 Chemical Irritant-induced Models of Itch, Contact Dermatitis, Eczema and Other Manifestations of Dermal Allergy, Hypersensitivity and/or Inflammation
Compounds of the formula (I) can be tested in animal models of contact dermatitis or itch, according to previously documented and validated methods, such as those described in the scientific literature (Saint-Mezard P et al. Eur J Dermatol 2004, 14(5): 284-95; Thomsen J. S., et al. J Exp Dermatol 2002, 11(4): 370-5; Weisshaar E, et al. Arch Dermatol Res 1998, 290(6): 306-11; Wille J J, et al. Skin Pharmacol Appl Skin Physiol 1999, 12(1-2): 18-27). Mice (or species such as guinea pig or rat) can be sensitized with 25 mL of 0.5% dinitrofluorobenzene solution (DNFB diluted 4:1 in acetone:olive oil immediately before application or other haptens, such as 12-myristate-13 acetate, picryl chloride, oxazolone, capsaicin, arachidonic acid, lactic acid, trans-retinoic acid or sodium lauryl sulfate) painted to the shaved dorsal skin or untreated (controls). Five days later, 10 mL of 0.2% DNFB a nonirritant dose) can be applied onto both sides of the right ear and the same amount of solvent alone onto the left ear. Ear thickness can be monitored daily using a caliper. Compounds of the formula (I) can be administered at the peak of inflammation to evaluate the anti-allergy activity of compounds. In addition, prophylactic or multiple dosing regimes can be utilized to evaluate the test compound for modulation of the onset and duration of anti-allergy activity. Variations of these tests can predict the anti-allergy and itch activity of effective clinical agents. The ability of these models to predict the therapeutic effect of compounds in human dermal conditions is supported by the cross-species ability of serotonin to induce itch (Weisshaar E, Gollnick H. Skin Therapy Lett 2000, 5(5): 1-2,5). Additionally, the contact sensitizing property of commercially important drugs and the ability of ion channel modulators to prevent and treat skin sensitization in these models (Kydonieus A, et al., Proceedings of the International Symposium on Controlled Release of Bioactive Materials 24th:23-24, 1997) demonstrate the therapeutic utility of compounds of the formula (I) in dermal sensitization.
Example 14 Chemical Irritant-induced Models of Rhinitis and Other Manifestations of Nasal Hypersensitivity and/or Inflammation
Compounds of the formula (I) can be tested in animal models of rhinitis, according to previously documented and validated methods, such as those described in the scientific literature (Hirayama Y, et al. Eur J Pharmacol 2003, 467(1-3): 197-203; Magyar T, et al Vaccine 2002, 20(13-14): 1797-802; Tiniakov R L, et al. J Appl Physiol 2003, 94(5): 1821-8). Testing can be conducted in mouse, guinea pig, dog or human in response to intranasal challenge with one or more irritants such as cold air, capsaicin, bradykinin, histamine, pollens, dextran sulfate, 2,4-tolylene diisocyanate, Bordetella bronchiseptica, Pasteurella multodica or acetic acid. In some cases, animals can be sensitized by pre-exposure to certain agents including, but not limited to, ragweed or ovalbumin. Prior to or following irritant administration, the test subject can receive, respectively, the prophylactic or therapeutic administration one or more times of compounds of the formula (I), or vehicle control, by the enteral or parenteral route. Significant differences indicative of nasal rhinitis or sensitization for the test compound-treated subjects compared with vehicle-treated subjects can be taken as evidence of anti-rhinitis activity. Independent variables include dose, frequency and route of administration, time interval between prophylactic or therapeutic test compound administration and irritant challenge as well as sex and non-sex genotype of the test subject. The intimate role of neurogenic inflammation in these hypersensitivity states demonstrates that compounds of the formula (I) desensitize or block the sensitization underlying these disease states.
Example 15 Conflict-induced Models of Anxiety, Panic Disorder and Other Non-adaptive Stressful or Phobic Responses
Compounds of the formula (I) can be tested in animal models of anxiety, panic disorders and other non-adaptive responses, according to previously documented and validated methods, such as those described by Cryan and Holmes (Cryan J F, Holmes A. Nat Rev Drug Discov 2005, 4(9): 775-90) or Braw et.al. (Y. Braw et al. Behav Brain Res 2006, 167: 261-269). Specifically, for studies in rats, the following apparati may be utilized: an open-field arena (62 cm×62 cm) enclosed by opaque walls (30 cm high) and plus-maze consists of two open arms, 50 cm×10 cm, and two enclosed arms, 50 cm×10 cm×40 cm with an open roof, arranged such that the two arms of each type are opposite each other. The maze is elevated to a height of 70 cm. The walls of the enclosed arms are made from black Plexiglas, while the floors from white Plexiglas. Videotape recordings can be analyzed using the ‘Observer’ system (Noldus Information Technology). A subject rat can be removed from its home cage, weighed and placed gently in the center of the open-field arena. The rat can be allowed to explore the open-field freely while its behavior is videotaped for 5 min. Afterwards, it can be transferred to the plus-maze and placed at the center, facing a closed arm. The rat's behavior can again be videotaped for 5 min, after which it can be returned to its home cage. The apparatus can cleaned using a 70% ethanol solution between rats.
Open-field and plus-maze measures can be grouped into two behavioral classes, namely ‘anxiety-like behaviors’ and ‘activity’. Open-field behavioral measures may include 1) Anxiety measures: % time in center square, % number of entries to center square (from total squares entered), % time freezing, latency to first freezing (freezing is scored when the subject is in an immobile state for at least 3 seconds; and 2) Activity measures: Total squares entered, number of rearings (standing on two hind legs), latency for first rearing. Plus-maze measures may include 1) Anxiety: % time in open arms, % number of entries to open arms (from total entries), number of unprotected head dips, latency to enter open arm; and 2) Activity: Total entries to all arms. Anxiety-like behaviors and activity can be analyzed by one-way ANOVA's on each of the measures, for each the between-subject comparisons. Plus-maze analyses can be conducted in a similar fashion.
Testing may also be conducted in mouse or rat in this fashion in order to measure avoidance of other aversive environmental stimuli such as Geller or Vogel anticonflict tests, the light/dark test and the hole-board test (see Cryan J F, Holmes A. Nat Rev Drug Discov 2005, 4(9): 775-90). Prior to environmental exposure, the test subject can receive the prophylactic administration one or more times of compounds of the formula (I), or vehicle control (e.g. 10% Solutol in sterile water), by the enteral or parenteral route. The cumulative time or number of times spent engaged in the aversive behavior can be measured. Significant differences in one or more of these measures for the test compound-treated subjects compared with vehicle-treated subjects can be taken as evidence of anxiolytic activity. Because these models are pharmacologically validated by the effectiveness of clinically useful anxiolytics (Cryan J F, Holmes A. Nat Rev Drug Discov 2005, 4(9): 775-90), they will be useful for the detection of anxiolytic compounds of the formula (I).
Example 16 Bladder Pressure- and Hypertrophy-induced Models of Urinary Incontinence
Compounds of the formula (I) can be tested in animal models of urinary incontinence according to previously documented and validated methods, such as those described by in the scientific literature (Kaiser S, Plath T, (Metagen Pharmaceuticals GmbH, Germany DE Patent 10215321; McMurray G, et al. Br J Pharmacol 2006, 147 Suppl 2: S62-79). TRPM8 is expressed in human prostate, testicle, seminiferous tubules, scrotal skin and inflamed bladder (Stein R J, et al. J Urol 2004, 172(3): 1175-8; Stein R J, et al. J Urol 2004, 172(3): 1175-8; Mukerji et al. BMC Urology 2006, 6:6). Excitation of TRPM8 receptors through cooling or application of menthol causes contraction in the bladder and a decrease in micturation threshold volume (Tsukimi Y, Mizuyachi K, et al. Urology 2005, 65(2): 406-10). To assess compounds of the formula (I) for potential urinary incontinence activity, Sprague-Dawley rats are surgically implanted with bladder catheters allowing for the delivery of fluid (typically saline) and the monitoring of pressure (using a pressure transducer). Cystometry recordings can be monitored with a polygraph to evaluate voiding interval, threshold pressure, bladder capacity, bladder compliance, and the number of spontaneous bladder contractions. For example, the bladder catheter can be connected to a Harvard infusion pump, and bladders perfused overnight with saline at 2 mL/h. The next morning the bladder catheter can be attached (using a “T” connector) to a Statham pressure transducer (Model P23 Db) and to a Harvard infusion pump. A plastic beaker attached to a force displacement transducer (Grass FTO3) can be placed under the rat's cage to collect and record urine volume. The cystometric evaluation of bladder function can be started by infusing saline (20 mL/h) and after the first micturition the infusion is maintained for 20 min. Two hours after the first cystometry period, the rats can be dosed orally with compounds of the formula (I) and a second cystometry is performed between 30 min and 4 h after administration of test compound. The appropriate vehicle (e.g. 10% Solutol in sterile water) can be similarly administered to groups of rats that served as controls and the cystometry can be performed at the same respective time points.
Compounds of the formula (I) can also be evaluated under conditions of bladder hypertrophy and instability. Under anesthesia, a silk ligature is tied around the proximal urethra of rodents producing a partial outlet obstruction and subsequent hypertrophied bladder development within 6-9 weeks (Woods M. et al., J Urology 2001, 166:1142-47). Cystometry recordings can then be evaluated as described above. Such preclinical procedures are sensitive to compounds having clinical utility for the treatment of urinary incontinence (Soulard C, et al. J Pharmacol Exp Ther 1992, 260(3): 1152-8), and the activity of compounds of the formula (I) in this model would be predictive of clinical utility.
Example 17 In vivo Model for Cold-enhanced Central Pain States
Injury to the brain or spinal cord, such as that caused by trauma, interrupted blood flow or neurodegenerative diseases, often precipitates a central pain condition. Examples of such injuries characterized, in part by, a hypersensitivity to cold stimuli include multiple sclerosis (Morin C, et al. Clin J Pain 2002, 18(3): 191-5; Svendsen K B, et al. Pain 2005, 114(3): 473-81), stroke or cerebral ischemia (Greenspan J D, et al. Pain. 2004, 109(3): 357-66) and spinal cord injury (Defrin R, Ohry A, Blumen N, Urca G. Pain 2001, 89(2-3): 253-63; Defrin R, et al. Brain 2002, 125(Pt 3): 501-10; Finnerup N B, et al. Anesthesiology 2005, 102(5): 1023-30). Each of these conditions may be readily modeled in animals for assessment of the ability of compounds of the formula (I) to mollify the hypersensitive state. For example, a spinal cord injury (SCI) can be performed in adult Sprague-Dawley rats having a body weight of 150-200 g at time of surgery (Erichsen et al. Pain 2005, 116: 347-358). The rats can be anaesthetized with chloral hydrate (300 mg/kg, i.p., Sigma, USA) and a catheter can be inserted into the jugular vein. A midline skin incision can then be made along the back to expose the T11-L2 vertebrae. The animals can be positioned beneath a tunable argon ion laser (Innova model 70, Coherent Laser Products Division, CA, USA) operating at a wavelength of 514 nm with an average power of 0.17 W. The laser light can be focused into a thin beam covering the single T13 vertebra, which can be irradiated for 10 min. Immediately before the irradiation, erythrosin B (Aldrich, 32.5 mg/kg dissolved in 0.9% saline) can be injected intravenously via the jugular catheter. Due to rapid metabolism of erythrosin B, the injection can be repeated after 5 min in order to maintain adequate blood concentrations. During irradiation, the body core temperature can be maintained at 37-38° C. by a heating pad. After irradiation the wound can be closed in layers and the skin sutured together.
SCI rats can be routinely tested for the presence of pain-like behaviors from 3-4 weeks after surgery. The fur of the animals can be shaved at least a day prior to examination of the cutaneous pain threshold to avoid sensitization of the skin receptors. During testing, the rats can be gently held in a standing position by the experimenter and the flank area and hindlimbs can be examined for hypersensitivity to sensory stimulation. On the day of drug testing, SCI rats can be administered drug according to the experimental schedule and the time course of pain-like behaviors can be measured. To test for the presence of cold allodynia, ethyl chloride or acetone can be sprayed onto the skin of the animals, often that which has been previously determined to be sensitive to mechanical stimulation by von Frey filament testing. The subsequent response to cold stimulation can be observed and classified according to the following scale: 0, no visible response; 1, localized response (skin twitch) without vocalization; 2, transient vocalization; 3, sustained vocalization. Kruskal Wallis ANOVA on ranks can be used to analyze the overall effects of non-parametric data obtained in response to cold stimulation following pretreatment with either compounds of the formula (I) or vehicle.
Example 18 In vivo Model for Post-anesthetic Shivering
Spontaneous post-anesthetic tremor that resembles shivering is common during recovery from anesthesia. Risks to postoperative patients include an increase in metabolic rate of up to 400%, hypoxemia, wound dehiscence, dental damage, and disruption of delicate surgical repairs. The etiology of spontaneous post-anesthetic tremor is most commonly attributed to normal thermoregulatory shivering in response to intraoperative hypothermia. In most operating and recovery rooms, shivering is controlled by the use of humidifiers, warming blankets, and inhalation of humidified heated oxygen. However, pharmacological control is an effective alternate treatment modality (Bhatnagar S, et al. Anaesth Intensive Care 2001, 29(2): 149-54; Tsai Y C, Chu K S. Anesth Analg 2001, 93(5): 1288-92). Compounds of the formula (I) may be assessed for their ability to mitigate post-ansethetic induced-shaking by using animal models such as that described by Nikki et al (Nikki P, Tammisto T. Acta Anaesthesiol Scand 1968, 12(3): 125-34) and Grahn (Grahn, D A, et al. J Applied Physiology 1996, 81: 2547-2554). For example, Wistar rats (males, weighing 250-450 g) may be surgically implanted with an EEG/EMG recording array to assess post anesthetic tremor activity. The EEG electrodes are located bilaterally 2 mm off midline and adjacent to bregma and lamda. Following a one-week recovery period, frontal-occipital EEG, raw EMG, and integrated EMG activities, as well as three temperatures (skin, rectal, and water blanket temperatures during anesthesia), and ambient temperature post-anesthesia can be monitored throughout the experiment using copper-constantin thermocouples. The EEG and EMG signals can be recorded on polygraph paper (5 mm/s, Grass model 7E polygraph) and, during recovery from anesthesia, the EEG is computer scored in 10 second epochs as either synchronized: high amplitude (0.100 μV), low frequency (1-4 Hz dominated) activity characteristic of slow-wave sleep (SWS-like) or desynchronized: low amplitude (75 μV), high frequency (5-15 Hz dominated), characteristic of waking and rapid-eye-movement sleep (W-like). The EMG activity can be quantified as the averaged summed voltage/time interval by processing the raw EMG signal through an integrator (Grass model 7P3, 0.5 s time constant). On the day of an experiment, the animal can be placed in a small acrylic box (15×15×15 cm) and exposed to a halothane vapor-air mixture (4% halothane). Immediately after the induction of anesthesia, the animal can be removed from the enclosure and subsequently anesthetized through a nose cone. Following cessation of anesthesia, two stages of recovery can be judged: emergence from anesthesia and restoration of behavioral activity (behavioral recovery). Emergence from anesthesia may be defined as an increase in tonic EMG activity and a change in the EEG from a SWS-like pattern to a W-like pattern. Behaviorally, recovery has occurred when the animal rises from a prone position and initiated coordinated movements. The time intervals from termination of anesthesia to emergence and behavioral recovery can be measured in all animals. Time interval data can be subjected to a repeated measure analysis of variance, and the Scheffe's method can be employed for testing differences between pairs of means.
Example 19 Cold-evoked Cardiovascular Pressor Responses
Compounds of the formula (I) can be tested in animals and humans for their ability to mitigate cardiovascular pressor responses evoked by cold exposure. Seasonal environmental cooling is directly associated with elevated blood pressure and an increased incidence of coronary events in human populations worldwide (Barnett, A G et al. J Epidemiol Community Heath 2005, 59 551-557). Cold-evoked pulmonary hypertention and cold aggravation of chronic obstructive pulmonary disease are clinical indications succeptible to heightened cardiopulmonary sensitivity to cold (Marno P et al. Eur Respiratory Review 2006, 15 (101): 185.; Acikel M et al Int J of Cardiol (2004) 97: 187-192). The clinical cold pressor test assesses changes in blood pressure (BP) and cold pain perception during a 2-3 minute immersion of one hand into ice water. This test may be utilized to characterize analgesic compounds (Koltzenberg M et al. Pain 2006, 126(1-3): 165-74) and to assess cold hypersensitivity (Desmeules J A et al. Arthritis Rheum 2003, 48(5): 1420-9). Compounds of the formula (I) can be studied in an anesthetized rat cold pressor paradigm to determine whether TRPM8 antagonism would interfere with the blood pressure pressor response to cold stimulation of the forepaws. Male Sprague-Dawley rats (300-450 g) anesthetized with sodium pentobarbital are instrumented with a jugular catheter and an indwelling carotid artery cannula connected to a pressure transducer. Vehicle (e.g. 20% HPbCD in sterile water) or test compound is infused (1 mL/kg) over one minute through the intravenous catheter. Ten minutes later both forelimbs are packed in crushed ice for 5 minutes. Alternatively, the test compound and vehicle treatments may be administered orally at an appropriated time prior to the surgical cannulations and cold challenge. Percent changes in mean arterial pressure in response to this cold stimulus are calculated for vehicle and test compound pretreatments. Percent inhibition attributed to treatment with test compound is then determined using the following formula: % Inhibition=[1-(cold evoked % change in BP post-test compound/cold evoked % change in BP post-vehicle)]×100. Results are shown in Table 11

Example 20 Cold-induced Vasoconstriction: Ramifications for Tissue Perfusion
Damage may occur to a bodily tissue when blood flow is compromised or interrupted. Reasons for vascular compromise include peripheral vascular disease (Lamah M et al, European journal of vascular and endovascular surgery (1999), 18(1), 48-51), prior traumatic or frostbite injury, Raynaud's syndrome (Lutolf, O et al Microvascular research (1993), 46(3), 374-82), diabetic neuropathy (Forst T et al, Clinical science (London, England: 1979) (1998), 94(3), 255-61.), surgical intervention and autonomic dysregulation (Gherghel D et al, Investigative opthalmology & visual science (2004), 45(10), 3546-54). In the case of marginal resting perfusion, vasoconstriction as enchanced by cool temperature may aggravate symptoms and potentiate tissue injury (Cankar K et al, The Journal of hand surgery (2000), 25(3), 552-8; LutolfO et al Microvascular research (1993), 46(3), 374-82.). Several of these conditions may be readily modeled in animals to assess of the ability of TRPM8 antagonists such as compounds of the formula (I) to preserve tissue perfusion in the face of local cooling. For example, laser Doppler assessment of skin blood flow may be studied in the paws of anesthetized rats (Hord A H et al, Anesthesia and analgesia (1999), 88(1), 103-8), wherein the paw is subject to a series of decreasing temperatures steps as applied by physical contact with a Peltier cooling element under computer control. The laser Doppler measures skin perfusion in the face of cooling-induced vasoconstriction thereby generating a temperature x perfusion relationship. Systemic administration of a TRPM8 antagonist is anticipated to shift this curve toward preserving perfusion at reduced temperatures relative to vehicle pretreatment. This activity is envisioned to be therapeutic in protecting tissue from hypo-perfusion and ischemia thereby minimizing the associated symptoms (e.g. pain) and potential tissue damage.
While the foregoing specification teaches the principles of the present invention, with examples provided for the purpose of illustration, it will be understood that the practice of the invention encompasses all of the usual variations, adaptations and/or modifications as come within the scope of the following claims and their equivalents.
